Pain Points and Solutions

Your Challenge:  Underground mining operations are always at danger of methane build-up and coal dust explosions, which may lead to catastrophic equipment failure and safety accidents.

Solution: YBS series Increased-safety motor is flameproof constructed with Ex d I Mb, especially designed for coal mine underground working area. Thickened cast-iron casing provides impact resistance, and multi-layer anti-rust coating protects against moisture and corrosive coal dust.

Your Challenge: Traditional motors create too much sparking and heat build-up, raising the danger of ignite in explosive atmospheres.

Our Solution: Our motors are designed with strengthened flameproof joint surfaces with precisely machined clearances and multi-channel sealing cable entrance mechanisms that prevent the escape of hot gas, thereby allowing safe operation even in the case of electrical failures.

FAQ

Q：What is YBS low voltage coal mine explosion-proof motor and its explosion-proof mark?

A：YBS series is low-voltage flameproof three-phase aSynchronous Motor dedicated to underground coal mines. Its standard explosion-proof mark is Ex d I Mb, designed for underground environments containing methane and coal dust mixture.

Q：What voltage standards does YBS low voltage mine motor adopt?

A：It belongs to low-voltage mining motor, standard voltages 380V, 660V, dual voltage 380/660V, 50Hz. 1140V high-voltage type is not covered in YBS series, customers requiring 1140V shall select YBK3 series instead.

Q：What energy efficiency and main technical parameters of YBS motor?

A：YBS reaches IE3 high efficiency level; frame size H80-H315, power range 0.55–200kW, 2/4/6/8 poles optional; protection grade IP55, F-class insulation, IC411 self-fan cooling, S1 continuous working system.

Q：What reinforced design does YBS have to adapt to underground harsh working conditions?

A：Thickened cast iron flameproof housing provides strong impact resistance against underground collision. Multi-layer anti-rust coating resists mine water, dampness and coal dust corrosion. Mine dedicated flameproof cable entry device includes multi-channel sealing. Reinforced flameproof joint surface with high precision clearance meets coal mine safety standards.

Q：What is the difference between YBS low voltage motor and YBK3 mine explosion-proof motor?

A：Voltage range differs: YBS only supports low voltage 380V/660V while YBK3 covers 380/660/1140V. Power coverage varies as YBS max power reaches 200kW, whereas YBK3 extends to 315kW with larger frame sizes. Application positioning targets different scales: YBS suits small and medium underground low-power equipment; YBK3 serves large transport and mining auxiliary equipment.
